function Install-LSUpdate { <# .SYNOPSIS Installs a Lenovo update package. Downloads it if not previously downloaded. .PARAMETER Package The Lenovo package object to install .PARAMETER Path If you previously downloaded the Lenovo package to a custom directory, specify its path here so that the package can be found .PARAMETER SaveBIOSUpdateInfoToRegistry If a BIOS update is successfully installed, write information about it to 'HKLM\Software\LSUClient\BIOSUpdate'. This is useful in automated deployment scenarios, especially the 'ActionNeeded' key which will tell you whether a shutdown or reboot is required to apply the BIOS update. The created registry values will not be deleted by this module, only overwritten on the next installed BIOS Update. #> [CmdletBinding()] Param ( [Parameter( Position = 0, ValueFromPipeline = $true, Mandatory = $true )] [pscustomobject]$Package, [ValidateScript({ Test-Path -LiteralPath $_ -PathType Container })] [System.IO.DirectoryInfo]$Path = "$env:TEMP\LSUPackages", [switch]$SaveBIOSUpdateInfoToRegistry ) process { foreach ($PackageToProcess in $Package) { $PackageDirectory = Join-Path -Path $Path -ChildPath $PackageToProcess.id if (-not (Test-Path -LiteralPath (Join-Path -Path $PackageDirectory -ChildPath $PackageToProcess.Extracter.FileName) -PathType Leaf)) { Write-Verbose "Package '$($PackageToProcess.id)' was not yet downloaded or deleted, downloading ...`r`n" Save-LSUpdate -Package $PackageToProcess -Path $Path } Expand-LSUpdate -Package $PackageToProcess -Path $PackageDirectory Write-Verbose "Installing package $($PackageToProcess.ID) ...`r`n" if ($PackageToProcess.Category -eq 'BIOS UEFI') { # We are dealing with a BIOS Update [BiosUpdateInfo]$BIOSUpdateExit = Install-BiosUpdate -PackageDirectory $PackageDirectory if ($BIOSUpdateExit.WasRun -eq $true) { if ($BIOSUpdateExit.ExitCode -notin $PackageToProcess.Installer.SuccessCodes) { Write-Warning "Unattended BIOS/UEFI update FAILED with return code $($BIOSUpdateExit.ExitCode)!`r`n" if ($BIOSUpdateExit.LogMessage) { Write-Warning "The following information was collected:`r`n$($BIOSUpdateExit.LogMessage)`r`n" } } else { # BIOS Update successful Write-Output "BIOS UPDATE SUCCESS: An immediate full $($BIOSUpdateExit.ActionNeeded) is strongly recommended to allow the BIOS update to complete!`r`n" if ($SaveBIOSUpdateInfoToRegistry) { Set-BIOSUpdateRegistryFlag -Timestamp $BIOSUpdateExit.Timestamp -ActionNeeded $BIOSUpdateExit.ActionNeeded -PackageHash (Get-FileHash -Algorithm SHA256 -LiteralPath (Join-Path -Path $PackageDirectory -ChildPath $Package.Extracter.FileName)).Hash } } } else { Write-Warning "Either this is not a BIOS Update or it's an unsupported installer for one, skipping installation!`r`n" } } else { switch ($PackageToProcess.Installer.InstallType) { 'CMD' { # Correct typo from Lenovo ... yes really... $InstallCMD = $PackageToProcess.Installer.Command -replace '-overwirte', '-overwrite' $installProcess = Invoke-PackageCommand -Path $PackageDirectory -Command $InstallCMD if ($installProcess.ExitCode -notin $PackageToProcess.Installer.SuccessCodes) { Write-Warning "Installation of package '$($PackageToProcess.id) - $($PackageToProcess.Title)' FAILED with:`r`n$($installProcess | Format-List | Out-String)" } } 'INF' { $installProcess = Start-Process -FilePath pnputil.exe -Wait -Verb RunAs -WorkingDirectory $PackageDirectory -PassThru -ArgumentList "/add-driver $($PackageToProcess.Installer.InfFile) /install" # pnputil is a documented Microsoft tool and Exit code 0 means SUCCESS while 3010 means SUCCESS but reboot required, # however Lenovo does not always include 3010 as an OK return code - that's why we manually check against it here if ($installProcess.ExitCode -notin $PackageToProcess.Installer.SuccessCodes -and $installProcess.ExitCode -notin 0, 3010) { Write-Warning "Installation of package '$($PackageToProcess.id) - $($PackageToProcess.Title)' FAILED with:`r`n$($installProcess | Format-List | Out-String)" } } default { Write-Warning "Unsupported package installtype '$_', skipping installation ...`r`n" } } } } } } |
